NPC

An NPC is a Non-Player City. An NPC, also known as a Barbarian's Town, does not belong to any alliance and has uniform regenerative properties. The level of an NPC indicates the maximum number of defensive units, troops, and resources to be found within.

Barbarian is a term for an uncivilized person, often used pejoratively, either in a general reference to a member of a nation or ethnos, typically a tribal society as seen by an urban civilization either viewed as inferior, or admired as a noble savage. In idiomatic or figurative usage, a "barbarian" may also be an individual reference to a brutal, cruel, warlike, insensitive person.
The term originates in the ancient Greek civilization, meaning anyone who is not Greek". Comparable notions are found in non-European civilizations. Barbarian cities were settlements where barbarians lived.

NPC Loot and Transports Needed by Level

Note: The research Privateering does not alter the amount of loot you will gain from hitting Barbarian towns, as they do not contain a warehouse.
The numbers below assume 0 capacity from other troops to bring back plunder. Even Ballistas can bring back some plunder if the NPC is not far away from the attacking city. For example, an NPC 5 that is 1 mile away can be plundered completely with 397 Transporters and 300 Ballistas when Logistics level is 10, and you use a Hero with Attack attribute 140 or greater. An NPC 7 that is 1 mile away can be plundered completely with 580 Transporters when 84K Archers with rainbow are sent with the Transporters and less than 10K troops are casualties.

Note: These numbers are subject to change. For example, a Level 5 NPC now only has 450,000 gold.

NPC Behavior

Attack / Aggression

Barbarian Towns will NEVER EVER attack cities. However, if you try transporting to someone of much higher prestige, there is a possibility of your transport caravan getting attacked by barbarians. If they succeed, your transport caravan will be taken out, whether it be transporters or warriors and so on. They may all be killed and the resources will be taken. Often exactly half of the troops and resources will be taken. You will be notified of this in a plunder report listed in black text (Note how normal plunder reports are listed in red text.).

Regeneration

It takes an NPC 8 hours to regenerate all of its resources.

It takes an NPC 1 hour to regenerate all of its defenses, troops and fortifications, at a rate of 10% every six minutes (the same six minute mark that your taxes are collected).

NPC Farming

NPC farming is the process of harvesting the benefits of attacking NPCs. NPCs yield two kinds of benefits: experience and resources. The specifics of the NPC farming process are covered in the section Plundering NPCs.

For maximum yield and efficiency, you will want to have as many zero-loss NPCs as close to your city as possible, to minimize the time wasted due to unit movement. For stronger players, having very high level NPCs close by produces very high returns at a predictable and efficient rate of loss. Building new NPCs is an option for cities with nearby flats.

Farming NPCs for experience

Higher level NPCs are like steroids for heroes. Since defeating NPCs gives your hero experience, and experience allows advancement in level, and advancement in level results in additional attribute bonuses, it is appropriate for all heroes to be developed through NPC farming.

Since NPCs fully regenerate their fortifications every hour, they can be attacked 24 times a day if you want to gain maximum experience for your hero.

Farming NPCs for prestige

you can farm NPCs for prestige by attacking them with warriors you will gain a few hundred prestige (from low leveled NPC's) to over 15k prestige (high leveled NPCs). I recommend this formula for the number of warriors to use:(NPC level)* 11000/(hero Att/100)except for level 9-10 NPC's where the formula is :(NPC level)* 11000/(hero Att./150)

WARNING The given formula for Lv.9-10 NPC is either outdated or simply wrong. Here is an example that demonstrate it:
110k Warrior wave with 251 ATT Hero (201+50 from Excalibur). The formula suggested ~65k Warriors. The attack resulted in total loss with little casualties made to the defending NPC

to correct someones edit above the higher the loss the more exp. including complete loss. while prestige must be a win, anything over 90 rounds yields highest prestige. more importantly one city with level 2 town hall farming 10 npc yields 40k prez to over a 100k prez per hit. requires a trusting friend to hold your citys and heros tho. further this can also be done with 99k warriors, 1k transports, on lvl 9 npc, with loss 12k to 70k. (once have instant war who cares how many, the exp is great). --Stalker 04:45, 27 October 2010 (UTC)Stalker

Farming NPCs for Resources

NPCs are the grocery stores of Evony. Think of transporters as your shopping cart, and ballista as your charge card that, if used correctly, never runs out.

Since NPCs regenerate all their resources in 8 hours, they can be farmed for full yield 3 times a day.

NPCs can actually be attacked 4 times a day - after the server maintenance it fills up npcs so if you get an attack ready to hit just before and then straight after the maintenance this enables you to do it 4 times a day!!!!

Building new NPCs

You can build new NPCs if you are able to build a new town. An NPC is nothing more than an abandoned player city. The level of the NPC will depend on the level of flat it was before you took it over.. Say the Flat was a level 10, once abandoned the town would turn into a level 10 NPC.

Plundering NPCs

Lower level NPCs (1-5) can be plundered without losses by sending only a minimum number of ballista units for a given the level of NPC. Rainbowing (adding one or more of other troops in the attack force) for these NPCs isn't suggested since they'll just die on the first round against the NPC traps and abatis. If a battles reaches 100 rounds, you will be declared the loser and sent home with nothing, even if you have taken no losses.

Higher level NPCs (6+) will always incur some losses.

Since NPCs regenerate all their resources in 8 hours, they can be farmed for full yield 4 times a day as they also regenerate resources after maintenance so time the attacks right just before and after the maintenance.

Since NPCs fully regenerate their fortifications every hour, they can be attacked 24 times a day if you want to gain maximum experience for your hero.

Plundering NPCs without Ballistas

Althought ballistas are the best way to farm NPCs there are times when you need to plunder without having access to ballistas (or do not have enough ballistas).
For those occasions (like in the beginning) it's recommended that you plunder low level NPCs (start with lvl 1, and then 2 when you've got enough transports and/or workers to carry the resources from a lvl 2 NPC) with a lot of warriors. Since you'll lose some (by traps etc) it's recommended to use warriors due to low costs and time to train. However, do not attack a NPC if you haven't got enough units to carry all resources back, using warriors will result in losses and you'll need to get every resource in order to be really effective.

Lvl 2 NPCs gives more resources than a lvl 1 NPC, but it also requires more warriors, which means longer training time. So always start producing warriors before you send your existing out on a raid, you'll always loose roughly 540 warriors on a lvl 1 NPC and 940 on a lvl 2 NPC.

Please note that I didn't keep count on my heroes attack levels while I did the research, but the ones on top have the least att value and the ones in the bottom have the most (however, the ones in the bottom of the lvl 1 npcs have almost the same att value as the ones in the bottom of the lvl 2 npc part.

As hero attack increases, the minimum number of units needed decreases.

A minimum archery level is needed for zero loss. As the attacker's archery level increases, so does the range of the ballista. The ballista need to shoot farther than the defending archer's towers.

As horseback riding level increases, so does the speed of the ballista. If the ballista advance too fast, they come into range of the defending archer's towers before eliminating them.

Do not let your Horseback Riding level get higher than your Archery level or your ballista will move into range of the Archer's Towers before the towers can be destroyed. For a quick reference, see the Reports for Archery vs. Horseback Riding Levels

Level 5 NPCs are much more sensitive to the Archery to Horseback Riding level ratio than level 1-4 NPCs.

If you upgrade to HBR level 10, you need a lot more ballista to win without losses. I had to multiply my previously used (level 9) numbers by 2.5.

Archery Level 10

NOTE: All of this information is based on old metrics. The game developers have since updated the attack statistics and made it a bit harder to attack NPCs. Also, attack metrics seem to vary from server to server. Talk with members of your alliance or other players on your server to get updated information on attack requirements to achieve 0 losses.
